Vedclass · Answer

(A) The resistance $R$ of a conductor is given by the formula $R = ho \frac{l}{A}$,where $ho$ is the resistivity,$l$ is the length,and $A$ is the cross-sectional area.Rearranging for resistivity,we get $ho = R \frac{A}{l}$.The unit of resistance $R$ is $\Omega$ (ohm),the unit of area $A$ is $m^2$,and the unit of length $l$ is $m$.Substituting these units,the unit of resistivity $ho = \Omega 	imes \frac{m^2}{m} = \Omega \ m$.Therefore,the $SI$ unit of resistivity is $\Omega \ m$.
